Forty percent of manufacturers reported that the economic conditions of export destinations were the key factor affecting exports.

Dr Noble Francis, economics director at the CPA, said: “The latest results highlight the strength of the UK economy in Q3, with private sector construction and manufacturing both benefiting.”

He continued: “Furthermore, as recovery in the construction industry has become more broad – across private housing, commercial and infrastructure sectors – growth in construction products has become more sustainable and manufacturers are optimistic going forward.”

Mr Francis added: “While product manufacturers reported growth in domestic sales, 27% of heavyside manufacturers suffered falls in export sales during Q3, and 40% of manufacturers reported that the key reason for this was the poor economic performance of the Eurozone – the key export destination for construction products.”
